Seachem Flourish Nitrogen 500ml

Results might be microscopic because after using it for bout a year I see no visual difference between the tanks I use the product on vs tanks I didnt use the product.

its awesome!

Cheaper than I expected and my plants looks pristine

I use Co2 injection and have a heavily planted tank. I have checked with 2 different products and it shows I have trouble keeping nitrates in my tank. Even with all my fish in my 55G, My plants absorb nitrates so much that I have to add some with this twice a week. Half cap each time.

this item arrived very quickly and performed well. what can you say about plant food? it worked well and I have nothing but appreciation for it.

Good price

This fertilizer comes in very handy in a 10 gallon single betta tank with very light nitrate bioload. I use the complete Flourish line following their suggested weekly dosing regimen and my plants are absolutely thriving!

Does the job. Plants never looked better.

This product does provide nitrogen to the aquarium but be aware its not super potent: Its 1% Nitrogen - 0% Phosphorous - 2% Potassium. The actual chemical content of this is potassium nitrate and iminium salt (urea). Im of the plant keeping school that says: test your water then add back the deficient nutrients as opposed to the estimative index school (but thats a debate for another forum). To hit 10ppm of nitrogen in a 55 gallon aquarium you need about 10.4ml of this product. Id suggest you look into using dry chemical potassium nitrate. It really is cheaper, easier to work with, and does the same thing (without the name brand label & price) I bought this, but blew right though it in no time because of the low concentration. I say 4 stars out of 5 because it is pretty expensive for how little nutrient youre getting.
